Question

The equilibrium constant, $\(K_c$ ) for the reaction $\({Cu_{(s)} + 2Ag^+_{(aq)} <=> Cu^{2+}_{(aq)} + 2Ag_{(s)} ; E^{\circ}_{cell} = 0.46 \, V}$ ) is

A

antilog 15.6

B

antilog 2.5

C

antilog 1.5

D

antilog 12.2

Answer

antilog 15.6

Explanation

Solution

$\(E_{cell}^{\circ} = \frac{0.0591}{n} \log \, k_c$ ) $\(0.46 = \frac{0.0591}{2} \log \, K_c$ ) $\(\frac{0.46 \times 2}{0.0591} = \log \, Kc \:\: \Rightarrow \: \log \, K_c = 15.56$ ) $\(\therefore \: K_c = {antilog\,15.6}$ )
